Jeong S, Hamilton S, Johnson M, Wu D, Turner A, Fischer M
Environ Sci Technol . 2025 Feb; 59(9):4376-4387. PMID: 39992284
Satellite data provides essential insights into the spatiotemporal distribution of CO concentrations. However, many atmospheric inverse models fail to adequately incorporate the spatial and temporal correlations inherent in satellite observations...

Jeong S, Fischer M, Breunig H, Marklein A, Hopkins F, Biraud S
Environ Sci Technol . 2022 Apr; 56(8):4849-4858. PMID: 35363471
California's dairy sector accounts for ∼50% of anthropogenic CH emissions in the state's greenhouse gas (GHG) emission inventory. Although California dairy facilities' location and herd size vary over time, atmospheric...

Wu H, Li Z, Li H, Luo K, Wang Y, Yan P, et al.
Natl Sci Rev . 2021 Oct; 8(3):nwaa157. PMID: 34691590
A new mechanism of new particle formation (NPF) is investigated using comprehensive measurements of aerosol physicochemical quantities and meteorological variables made in three continents, including Beijing, China; the Southern Great...

Lebel E, Lu H, Vielstadte L, Kang M, Banner P, Fischer M, et al.
Environ Sci Technol . 2020 Oct; 54(22):14617-14626. PMID: 33125216
California hosts ∼124,000 abandoned and plugged (AP) oil and gas wells, ∼38,000 idle wells, and ∼63,000 active wells, whose methane (CH) emissions remain largely unquantified at levels below ∼2 kg...

Guha A, Newman S, Fairley D, Dinh T, Duca L, Conley S, et al.
Environ Sci Technol . 2020 Jul; 54(15):9254-9264. PMID: 32633497
This study derives methane emission rates from 92 airborne observations collected over 23 facilities including 5 refineries, 10 landfills, 4 wastewater treatment plants (POTWs), 2 composting operations, and 2 dairies...

Cui Y, Vijayan A, Falk M, Hsu Y, Yin D, Chen X, et al.
Environ Sci Technol . 2019 Jul; 53(16):9636-9645. PMID: 31347357
California methane (CH) emissions are quantified for three years from two tower networks and one aircraft campaign. We used backward trajectory simulations and a mesoscale Bayesian inverse model, initialized by...

Hu L, Andrews A, Thoning K, Sweeney C, Miller J, Michalak A, et al.
Sci Adv . 2019 Jun; 5(6):eaaw0076. PMID: 31183402
Long-term atmospheric CO mole fraction and δCO observations over North America document persistent responses to the El Niño-Southern Oscillation. We estimate these responses corresponded to 0.61 (0.45 to 0.79) PgC...

Cui X, Newman S, Xu X, Andrews A, Miller J, Lehman S, et al.
Sci Total Environ . 2019 Feb; 664:381-391. PMID: 30743131
Combustion of fossil fuel is the dominant source of greenhouse gas emissions to the atmosphere in California. Here, we describe radiocarbon (CO) measurements and atmospheric inverse modeling to estimate fossil...

Fischer M, Chan W, Delp W, Jeong S, Rapp V, Zhu Z
Environ Sci Technol . 2018 Aug; 52(17):10205-10213. PMID: 30071722
We estimate postmeter methane (CH) emissions from California's residential natural gas (NG) system using measurements and analysis from a sample of homes and appliances. Quiescent whole-house emissions (i.e., pipe leaks...

Mehrotra S, Faloona I, Suard M, Conley S, Fischer M
Environ Sci Technol . 2017 Oct; 51(21):12981-12987. PMID: 29019666
We report 65 individual measurements of methane emissions from 24 oil and gas facilities across California. Methane emission rates were estimated using in situ methane and wind velocity measurements from...
